18 year old started being bulimic

I'm 18 years old and im six foot tall and 210 pounds....and yes im a girl...i started being bulimic after i lost over 60 pounds one summer on one of these stupid diet plans...it was between the summer of my 8th and freshman year. when i got into highschool every one started noticing me because i was pretty. well i wanted to go out and eat junk food like the rest of my friends where so thats what i did...i gain five pounds and i realized i was just going to get fat again so i would eat whatever i wanted and just sneek into the bathroom and make myself vomit...and it worked....then i got tired of feeling sick...and my throat hurting all the time...and i gained so much wieght back...well then i got a bf and gained even more...well when my boyfriend left me after two years...i decided i need to lose wieght if anyone was going to love me or accept me...and my theory is..." Its not whats on the outside that matters its whats on the inside...but you have to have sumthin to look at on the outside for people to give you a time of day to see whats on the inside" so thats where im at...starting over again...and now i live on my own so its alot easier...dont eat infront of people and just pig out when i get home and throw up and then have a cig.
